An empty box weights 2 1/4 pounds. it is filled with 16 2/3 pounds of fruit. what is the weight of the box when it is fill?

In order to solve this problem, we need common denominators. 1/4 multiplied by 3/3 is 3/12. 2/3 multiplied by 4/4 is 8/12. 8/12 + 3/12 = 11/12. We also must add 2 and 16. 2 + 16 is 18. The box weights 18 11/12 pounds.

2 1/4 = 2 3/12

16 2/3 = 16 8/12

16 8/12 + 2 3/12 = 18 11/12

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
